LAND-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 751,106, dated February2, 1904.

Application filed April 6, 1903.

To all whom, it may concern:

Be it known that I, CHARLES E. REED, a citizen of the United States,residing at Sunnyside, in the county of Yakima, State of VVashington,have invented certain new and useful Improvements in Land-Scrapers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

' This invention relates to land-scrapers; and it has for its object toprovide asimple and eiiicient construction which will be held securelyin active position while in operation and which may be easily andquickly lowered to-discharge its lead at the proper time.

" A further and important object of the invention is to provide ashifting mechanism for the scraper-board which will be strong anddurable and will be held against lateral displacement on the base-boardand in which, furthermore, the shifting link may be adjusted verticallyor transversely of the scraper-board to satisfy difierent specificconditions of operation.

An additional object of the invention is to provide a more secure mannerof attaching or hinging the scraper-board to the base-board, so as toprevent pulling of the hinges from the scraper-board, and, further, toprovide spring-shoes at the ends of the scraper-board and on which saidboard will travel when it is shifted to dumping position.

Other objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in both views, Figure1 is a front perspective viewof the scraper with the scraper-board inraised position. Fig. 2 is a rear perspective view of the scraper-boardand a part of the base-board.

Referring now to the drawings, the present scraper comprises abase-board 5, at the end of which are secured the transversely-aliningears 7, forming part of the hinge connection between the base-board andthe scraper-board 8. The scraper-board is disposed transversely SerialNo. 151,309. (No model.)

of the base-board and slightly beyond its end, and upon the front faceof the scraper-board is secured a metal scraping-blade 9, which iscurved downwardly and forwardly beyond the lower edge of thescraper-board. ing with the perforated ears 7 are eyebolts 10, which areengaged through the scraper-board 8 and through the scraper-blade on thefront face of the latter, said eyebolts being drawn snugly into placewith their heads againstthe rear face of the scraper-board through themedium of nuts 11, which are engaged with their front ends and impingeagainst the front face of the scraper-blade. The heads of the eyeboltslie at the outer sides of the ears 7 and through the ears and eyeboltsis engaged a pintle-bolt 12, whereby a hinged connection is formedbetween the two boards. By engaging the eyebolts through thescraper-blade the drawing of the eyebolts from the scraperboard andconsequent loosening of the hinge connection is absolutely prevented.

The scraper-blade is' held to the scraperboard not only by means of theeyebolts, but further by means of bolts 13, which are 'engaged throughthe scraper-board, the scraperblade, and the metal straps M, which aredisposed vertically on the front face of the scraper-board and havetheir lower ends displaced forwardly and overlapped upon the front faceof the scraper-blade. The metal straps or braces are further held inplace by means of additional bolts 14: which are engaged through themand through the scraperboard'at points above the scraper-blade.

It will be noted that the straps let are disposed at the ends of thescraper-board and also at points between the ends thereof, and upon theend portions of the endmost straps are secured the inturned ends ofarc-shaped spring-metal plates 15, which are held to the straps by theend-retaining bolts or securingbolts of the straps. These spring-metalplates project forwardly at right angles to the scraper-board and formshoes or runners, which support the board free from the ground when theboard is shifted to dump its load, as hereinafter described. By formingthe shoes or runners of spring metal the board is not sub-Coiiperatjected to sudden shocks in such degree as to injure the boardor its hinge connection with the base-board.

When the scraper-board is in active position, it is erect, and to dumpthe materials scraped, so that the board may ride over it, the upperedge of the scraper-board is shifted forwardly. After the materialscraped has been dumped the scraper-board is returned to its uprightposition.

To shift the scraper-board, a lever 16 is provided, and is pivoted atits lower end upon the end of a fulcrum-plate 17, which is securedtransversely upon the base-plate 5 and projects laterally therebeyond.In the lever is a longitudinal series of transverse perforations 18,which are designed to receive interchangeably the pin 19, which isengaged through the arms 20 and 21 of a bifurcated link 22, said armshaving also lines of perforation therein, so that the pin or bolt may beshifted longitudinally thereof to vary the effective length of the link.The forward end of the link is bifurcated to receive an eyebolt 22,which is removably engaged through the metal plate 23, securedvertically against the rear face of the scraper-board, said plate havinga longitudinal series of perforations 24, which aline with correspondingperforations 25 in the scraper-board and which permit of engagement ofthe eyebolt with the scraperboard at difierent points of the height ofthe latter. As thelever is shifted upon its fulcrum the link is operatedto swing the scraper-board on its hinge to lie at difi erent angles tothe baseboard, and to hold the lever at difierent points of itsadjustment a notched segment 26 is provided, having its end portionsbent laterally and secured upon the top face of the baseboard. On theside of the shifting-lever is mounted a casing 27, in which is disposeda slidable spring-pressed bolt 28, which is held by its spring in normalengagement with the notched segment, there being provided an angularlatch-lever 29, which is pivoted at the upper end of the shifting-leverand is connected by the link 30 with the latch bolt, so that when theangular lever is operated in one direction the latch-bolt will bewithdrawn from the notched segment, and when the angular lever isreleased the latch-bolt will engage the notched segment. To preventlateral displacement of the shifting-lever from the notched segment, afinger 31, formed upon the casing 27, projects longitudinally from thecasing and lies against the opposite face of the notched segment fromthe shifting-lever.

When it is desired to adjust the shifting mechanism of the scraper-boardto satisfy different specific conditions, the shifting link may beconnected to the board at different points vertically thereof. It may beconnected to the shifting-lever at difierent points vertically thereof,and the effective length of the shifting link may be changed.

Drag-bars 31 are pivotally connected with eyebolts 32, which are engagedthrough the scraper-plate and scraper-board and are adapted at theirforward ends for attachment of draft appliances.

It will be understood that in practice modifications of the specificconstruction shown may be made and that any suitable materials andproportions may be used for the various parts without departing from thespirit of the invention.

What is claimed is In a land-scraper, the combination of a baseboard, ascraper-board hinged transversely to the base-board, a scraper-blade atthe lower edge of.the scraper-board, transverse braceplates disposedupon the front faces of the scraper-board and the scraper-blade,springshoes disposed with their ends upon the braceplates,attaching-bolts passed through each shoe at one end and through abrace-plate and the scraper-board and at the opposite end through theshoe, the brace-plate, the scraperblade and scraper-board, and meansmounted upon the base-board and connected with the scraper-board forshifting the latter.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES E. REED.
